Some additional information:
It is a 1958 one-off by Monsieur Bastien from Pessac. It is based upon mechanics of the Renault 4 CV. The engine was slightly tuned. The body was made of polyester. Although the car was larger than the 4 CV (3.90 m long, 1.45 m wide), it weighed only 420 kg, thanks to a tubular frame.
